Product description
Flux-cored wire for gas-shielded arc welding
Developed for the assembly and repair of gray, malleable, nodular or phosphorous cast irons
Also suitable for heterogeneous cast-iron-steel assembly
Suitable for welding massive or heavily flanged parts
Preheating is not required.
The energy input is low, limiting the heat-affected zone.

Why choose this cored wire?
-
Very high resistance to cracking
➤ Thanks to its nickel and cerium composition, it effectively absorbs the internal stresses associated with welding cast iron, even on thick or old parts. -
Highly ductile (non-machinable) deposit
➤ Welded metal remains flexible and fracture-resistant, perfect for structural repairs without mechanical finishing. -
Excellent weldability and bead cleanliness
➤ Coating optimized for gas welding (typically Ar + 2-5% O₂), enabling a stable arc, low spatter, and even melting. -
Good tolerance to contaminated cast irons
➤ Cerium acts as a refiner, helping to weld oxidized, oiled or harder-to-clean cast irons. -
Low dilution, avoiding hard or brittle areas
➤ Very good metallurgical behavior, limiting the risk of cracking in the heat-affected zone.
